The slide WT is attached tothesideof the fra which passes through-a slot, c, i n the slide, allowing it a limited back-andfforth moveconnections. ",Thejsame-'part is marked bythe same letter 'of reference-wherever it occurs v .The `nature of ymy'invention 'consists in .improvernent's in machinery for jointing' staves by means ofv saws, whereby it` i's rendered sol 'perfectly adjustable that stavesof any width' 'can be'jointed lin a superiorv manner'without unnecessary- 'yvns't'e' of material, while 'each stave receives abilge and-bevel'proportionate to its width,-a1l substantially as hereinafter- 4more-fully described. Y To enableothers t, make and use 'my ini# proved machine, I will' proceed to deseribeits vconstruction and operatiomreferring tothe drawings, Whereon Ajlnarks the iframe ofthe Fig. 5'is a detail view of the` side Wand its projectingu'p'from the' end ot slide IV, is inv such a positionas to be acted upon alternately by the stops m. and u of the carriage Y, assaid Icarriagevreciprocates lon the Ways A A2.

When the sawing of the joints is completed, the stop u on the carriage Y comes in contact with the dog l of slide Wg-'and causes that slideto Y operate the wheel S. on shaft R, so that, by

means of the gears Q, and P, the shaft N shall be so turned as," to depress the lever M and throw the .saws K- K{ a little farther apart at top, so that, as the carriage Y is drawn back, the edges of the jointed stave will not come into contact with the saws. riage arrives at its startingpoint, the stopm comes into contact with dog' l, and restores the wheel S and, through it, the saws to rtheir original position, ready for a repetition' of the operation.
